Hello,
I've released version 2.0.9 of the legacy version of Prolog+CG.
http://prologpluscg.sourceforge.net/
Most users should switch to the version under Amine Platform, <http://amine-platform.sourceforge.net/>.
This version sees the following changes over 2.0.8:
1) The manual has been completely redone in LaTeX, thereby supporting PDF generation. It has been reformatted for more natural navigation, and now uses latex2html to translate to HTML. The manual is in the root directory of the distribution.
2) The program no longer generates .obj files; it simply recompiles the program whenever it needs to. With today's fast computers, the .obj files were becoming more of a liability than an asset, due to bugs in the code as well as problems with generating .obj files underneath "C:\Program Files\" on Windows 2000 and Windows XP (problems with permissions).
3) A bug was fixed in concat/3. See the ChangeLog for details if you want to know what it was.
Enjoy!
